Arsenal boss Arsene Wenger has fired a Premier League warning at Pep Guardiola.
The Bayern Munich coach will take charge of Manchester City next season.
Wenger believes the Spaniard could find Premier League life more difficult than his previous roles at Barcelona and Bayern Munich.
He said: "If you look at the tendency in the Premier League it looks difficult to have a high win percentage.
"The Premier League is more difficult than any other league."
